A Wesleyan University student who says she was raped in front of onlookers at a `` wildly out of control '' campus fraternity party has filed a lawsuit against Xi Chapter of Psi Upsilon , 11 of its members and the alleged assailant , according to court documents .

Cabri Chamberlin , then a freshman , said she was raped by another student last May at the Xi Chapter of Psi Upsilon fraternity house in Middletown , Connecticut , at a pledge `` strip show , '' says the suit , which was filed Tuesday in a Connecticut federal court .

CNN does not usually identify victims of sexual assault but has done so in this case because the woman wanted to make her name public .

`` I 'm proceeding in this case with my real name instead of ` Jane Doe ' because as the victim of a heinous violent crime I 've done nothing wrong and have nothing to be ashamed of , '' Chamberlin said in a statement provided by her lawyer . `` I ca n't even describe the pain of being raped , or how much it alters a life , and no other person should ever be forced to have that experience . I hope my experience and lawsuit will create changes that protect others . ''

At the party , the lawsuit says , many `` underage and extremely intoxicated '' young people danced with naked pledges and `` spilled alcohol throughout the area . ''

Chamberlin , who has taken a leave from her studies , said she became extremely uncomfortable , put on her jacket and attempted to leave when a male student picked her up from behind and raped her in the presence of `` numerous others , '' according to the lawsuit .

Wesleyan public safety officers then took her to a nearby hospital , where a diagnosis of sexual assault was documented , the lawsuit says .

`` Psi Upsilon Fraternity takes all reports of risk management violations , especially those with regard to sexual assault , very seriously , '' Tom Fox , executive director of Psi Upsilon Fraternity , said on the fraternity 's website . `` We are currently investigating the incident and gathering further information . ''

After an internal investigation , the university expelled the alleged perpetrator and imposed `` sanctions against the fraternity and members , '' according to a statement by Wesleyan President Michael S. Roth .

The student named in the lawsuit , who has not been charged criminally , did not return calls seeking comment .

Middletown police confirmed that they responded to a sexual assault complaint from the Psi Upsilon Fraternity house on May 4 , 2013 , spokeswoman Lt. Heather Desmond said . The investigation is ongoing , and no charges have been filed , she said .

Desmond said police were having difficulty finding witnesses and urged anyone who attended the party from May 3 into May 4 and may have witnessed anything to call police .

The lawsuit says the fraternity contractually demands self-governance from Wesleyan , relinquishing the public safety and housing services the university generally provides to students .

The fraternity allegedly failed to adequately provide its own security , and the defendants failed to train themselves in safety and risk management issues , including sexual abuse prevention , hazing and the misuse of alcohol , according to the lawsuit .

Chamberlin 's lawyer , Douglas Fierberg , said that because the fraternity sets itself apart from the university , officers from the university 's Department of Public Safety can enter the fraternity only in `` exigent circumstances '' or when specifically asked to come in .

`` This lawsuit seeks to hold this fraternity responsible for its gross mismanagement which it does under the guise of self-management , '' Fierberg told CNN . `` Fraternity self-management has historically proven itself to be flawed and dangerous . Women have been raped because of this mismanagement . People have died because of this mismanagement . And this victim will hold the fraternity responsible for its tradition of dangerous mismanagement . ''

Wesleyan University would not comment on the fraternity 's arrangement with the Department of Public Safety , but Roth 's statement acknowledged that the university 's fraternities have `` some autonomy . ''

`` All have seen increased scrutiny over the past few years , '' Roth said of fraternities . `` We intend to focus our attention on improving the safety of these spaces . ''

Wesleyan University was not named in the lawsuit .

`` On behalf of the university community , I want to express our horror at this shameful assault , '' Roth said in the statement . `` Sexual violence will never be tolerated on our campus . Sexual violence on college campuses is a national problem , and it 's important to raise awareness about this issue . At Wesleyan we are committed to caring for survivors , vigorously pursuing perpetrators , and creating a positive campus climate in which sexual violence and misconduct have no place . ''

Chamberlin has taken a leave of absence from the university since the attack and is receiving `` intensive counseling , trying to pull her life together , '' her lawyer said .

Chamberlin is seeking $ 10 million in damages , the lawsuit says .

In 2012 , a Wesleyan student sued the university and another fraternity , which Wesleyan no longer recognizes as a student organization , after she said she was raped in its frat house two years before . The fraternity had garnered the on-campus reputation as the `` Rape Factory , '' according to the lawsuit . Her assailant pleaded guilty to assault and unlawful restraint , court papers said .

The case was settled in court-ordered mediation in August 2013 .
